I am Rahul Welcome to my youtube channel Civil Notebook.
About this video-
Dosto is video me app logo ko types of cement ke bare me batayunga.
Ordinary Portland Cement (OPC)
Portland Pozzolana Cement (PPC)
Rapid Hardening Cement
Quick setting cement
Low Heat Cement
Sulphates resisting cement
Ordinary Portland Cement (OPC)
In usual construction work, Ordinary Portland Cement is widely used. The composition of Ordinary Portland Cement:
Argillaceous or silicates of alumina (clay and shale)
Calcareous or calcium carbonate (limestone, chalk, and marl)
Uses of Ordinary Portland Cement
It is used for general construction purposes.
It is also used in most of the masonry works.
Portland Pozzolana Cement (PPC)
Pozzolans are natural or synthetic materials that contain silica in reactive forms. It reacts with calcium hydroxide generated by hydrating cement to form additional cementations materials when it is finely divided. The composition of Portland Pozzolana Cement:
OPC clinker
Gypsum
Pozzolanic Materials (Fly ash, volcanic ash, and Calcined clay or silica fumes.)
Uses of Portland Pozzolana Cement
PPC is usually used in hydraulic structures, marine structures, construction near the seashore, dam construction etc.
It is also used in pre-stressed and post-tensioned concrete members.
As it gives a better surface finish, it is used in decorative and art structures.
It is also used in the manufacture of precast sewage pipes.
Rapid Hardening Cement
When finely grounded Tri-calcium silicate (C3S) is present in OPC with higher content, it gains strength more quickly than OPC. This type of OPC is called Rapid Hardening Cement. It’s initial Setting Time 30 minutes and Final Setting Time 600 minutes.
Uses of Rapid Hardening Cement
Rapid hardening cement is mostly used where rapid construction is needed like the construction of pavement.
Quick Setting Cement
Quick setting cement is the cement which sets in a very short time. The initial setting time is 5 minutes and the final setting time is 30 minutes. The composition of Quick Setting Cement:
Clinker
Aluminium sulphate (1% to 3% by weight of clinker)
The aluminium sulphte increase the hydration rate of silicate.
Uses of Quick Setting Cement
It is used in underwater construction.
It is also used in rainy & cold weather conditions.
It is used a higher temperature where water evaporates easily.
Used for anchoring or rock bolt mining and tunneling
Low Heat Cement
It is a spatial type of cement which produce low heat of hydration during setting. Some chemical composition of Ordinary Portland Cement is modified to reduce the heat of hydration. The chemical composition of low heat cement:
A low percentage (5%) of tricalcium aluminate (C3A)
A higher percentage (46%) of declaim silicate (C2S).
Uses of Low Heat Cement
It is used for the construction of dam’s large footing, large raft slabs, and wind turbine plinths.
It is also used for the construction of chemical plants.
Sulphates resisting cement
Sulphet resisting cement is used to resist sulphet attacks in concrete. Due to the lower percentage of Tricalcium aluminate, the production of calcium sulpho-aluminates gets reduced.
Uses of Sulphates resisting Cement
Construction in contact with soils or groundwater having more than 0.2% or 0.3 % g/l sulphate salts respectively.
Concrete surfaces subjected to alternate wetting and drying such as bridge piers, concrete surface in tidal zone, apron, Building near seacoast.
Effluent treatment plans, Chimney, Chemical industries, water storage, sumps, drainage works, Cooling towers, Coastal protective works such as sea walls, breakwaters, tetrapods etc.
Ummeed Hai Aapko Ye Video Bahut Pasand Aayegi.
Thank you so much.
Mst bro
Good explanation 😊
Thank you
Very informative
Tq😊
Is there any liquid or cement I can use to fill my hollow tile that has come out from edge and shaking?
White cement
What is c3A and the other other thing !
Fy% in PPC cement is 15-35% in india
Any reference books for this knowledge? Plz.. Sugest.

Who established cements?

Iske pehale ke video ka to pata nhi but ye video dekhaneke baad bakike dekhana nhi hai. Bas likha hua padke batana is one educate someone else ye to school, college n tuition me Hotahi hai. Need of improvement in your teaching bro no hard feelings ha.😇
